WATER HEATER AND PURIFIER.

SPECIFICATION forming part of Letters Patent N o. 591,505, dated October 12, 1897. Application filed December 13, 1893. Serial No. 493,567. (No model.)

T0 all whom, t may concern.-

Be it known that we, WILBUR L. SHEPARD and ERAsTUs W. WHITLOCK, of Elmwood, in the county of Hartford and State of Connecticut, have invented certain new `and useful Improvements in Water Heaters and Purifiers, of which the following is a full, clear, and exact description, whereby any one skilled in the art can make and use the same.

The object of our invention is to provide an apparatus that may be used for'heating water for any purpose and one that shall be accessible and readily cleaned as to the interior.

The apparatus is particularly applicable for use as a boiler feed-waterv heater and puriiier, although applicable for heating water for any ordinary mercantile use.

To this end our invention consists in the details of the several parts making. up the apparatus as awhole and in the combination of such parts, as hereinafter described, and

more particularly pointed out in the claims.k

Referring to the drawings, Figure l -is a de'- tail view, in central section, ofthe feed-water heater shown as connected to lan' exhaust-,

Fig. 2 is a detail plan View of the same with the upper chamber removed.

In the accompanying drawings the letter a denotes the body of the heater, composed usually of a cylindrical shell of wrought or cast metal having at the opposite extremities iianges a', through which bolt-holes may be made for the purpose of securing the end sec- This heater-body is usually placed in an upright position and is secured at the lower end to a flange b', formed around the outer edge of a sediment-chamber b. 4This chamber is made with curved or sloping walls, preferably tapered or funnel-shaped, as shown in the drawings, and being made graduallysmaller in cross-section from the upper edge toward the 5o let c, that consists of a pipe connected' up to the bottom of the heater and provided with a suitable check-valve d.

At the upper en'd of thebody of the heater a cover is provided that is made up of a scumchamber e, the shell forming the chamber having a flange e', through which bolts f are passed for the purpose of securing to it the ange a' on the body part of the heater. This scum-chamber is made, preferably, in the form of a conical frustum, as shown, but in any event is made smaller in area near the blowvolf outlet e2 than near the'edge secured to the body of the heater.

The object of this chamber is to provide ka space in which the lighter impurities found in water (such as magnesium) may accumulate in a convenient position to be readily blownoff.

To the outlet e2 a suitable Vblow-olf pipe g is connected and is provided with any suitable valve to control the discharge. This discharge-valve in the outlet-pipe may be in the form of a safety-valve h. .Through the Walls of the body part of the heater and preferably near the lower end a water-inlet pipe 'i is provided for the discharge into the heater of water from any suitable sourceof supply either from the boiler feedpump or from any other source under pressure.

Near the upper end of the heater,- but at a point from which comparatively pure water may be drawn, an outlet-pipe j is connected, and through this latter. pipe the heated water passes to any desired point.

The Water being supplied to the heater under pressure it is obvious that some means must be provided for controlling the discharge of water therefrom to provide its delivery in suitable quantities, and this means may consist of any well-known device.

In case the apparatus is used for heating boiler feed-water the discharge, of course, is made directly into the boiler.

Arranged within the heater there is one or more coils of pipe 7c, each coil being connected 95 IOO impurities accumulate at the top of the conel e in form of a scum and the full pressure of water being turned on, or the pump started to cause a pressure of the water within the heater, the valve in the pipe g is open and the impurities blown oi therethrough. This valve is in the form of a safety-valvmas shown, so that should the discharge of Water A through the pipej be stopped and a pump or like device supplying water continue its operation any danger of bursting the heater by overpressure will be avoided.

XVe claim as our inventionl. In combination in a Water-heater, the shell, a cone-shaped cap secured to and with its axis in line With the axis of the shell and forming a tapered scum-chamber, a coil of pipes arranged Within the shell, and a blowoft' pipe extending through the Wall of the tapered cap at lthe highest part of the chamber, and with its axis in line with the axis of the cap and shell, all substantially as described.

2. In combination in a water-heater, a shell, a cone-shaped cap secured to and with its axis in line with the axis of the shell and forming a tapered chamber, a coil of pipes arranged Within the shell, a bloW-oi pipe eX- tending through the Wall of the tapered cap at the highest part of the chamber and with its axis in line With the axis of the cap and shell, and an outlet from the shell located below the line of Water-level in the boiler.
